With the rapidly growing demand for oil in China, the stage is set for conflict between the Chinese and America, currently the largest consumer of fossil fuels in the world.
I don't see it. The USA and China have a special trade relationship whereby the Chinese send us semi-worthless consumer goods and in return we send them semi-worthless pieces of paper. Each country is getting what it needs from the other so why fight? Oil? I doubt it. Unless the Chinese are planning to switch to an automobile society soon they will never need as much as we currently use. And I'm betting our usage declines over the next 30-50 years.
There have been predictions of WWIII ever since the late '40's. Each generation thinks that the perils they face is worse than any that have come before. They are almost always wrong about that.
